What kind of LED do you use to grow vertically?

Convective cooling would work fine across the large surface area of a Quantum board. Again, the air picks up the heat and rises, carrying it away.
Frankly, I'd expect the board to run cooler run vertically than flat.
@robincnn would you care to do a bit of testing to see which orientation runs cooler? I think the results might surprise some people.
Testing Vertical orientation here.

Folks seem stuck on round cylinders and forcing directing lighting to be something it isn't- namely, omnidirectional.

Why not instead simply run LED lights onto flat trellis panels?
Are you suggesting running a single plane of trellis? Wouldn't you want a multi sided light to cover every wall with trellis? Running a single plane vertically under a led doesn't seem advantageous to running it horizontally.

And running passive heat sinks vertically could cause the high end to run hot, where flat mounted sinks tend to cool evenly. Assuming there's enough active air flow in the room, I don't think it should be an issue, but ymmv.

To your first point, look at the square footage OF THE FLOOR the vertical flat plane approach takes up relative to doing the whole thing flatlander style- or cylinders either, for that matter.

To your second point, have a gander at:

@robincnn himself just did a vertical vs horizontal cooling test. The vertical board runs cooler, not warmer. Your concerns about the top being warmer than the bottom smacks of the perfect being the enemy of the already clearly better. In fact this arrangement creates its own convective air current, obviating the need for external fans.

Finally, flat mounted heat sinks are demonstrably hot in the middle and coolest at the corners; hardly 'even'.

are those quantums available in specific spectrums? i'd like to be able to get a couple in far red instead of wiring a series of tiny diodes.

Who's to say they wouldn't be used vertically? I only asked because they were posted about by you and others in here

You're asking a parts question, which is better asked and answered elsewhere. This is a thread about how to use the panels once you have them. Discussion about the effects of using red LED light in a vertical setting, for example, would be most welcome.

If you keep asking questions in the wrong places, you'll be liable to receive less information of lower quality. That's just the way information works, bro.

Ok, got it. Now I can picture a wall of modules stacked sideways, each module has trellis on one side, led panels on the other, hydro res on the bottom, pull out like a pocket door. Led panel would then swing out of the way for canopy maintenance. Maybe 3 panels in the space a typical 4x4 tent takes up?

Am I wrong in thinking leds are slightly disadvantageous in vertical due to not being a single 360deg light source? I always thought that was the biggest reason to go vert.

Interesting. I'm going off personal experience also. I used to build machines that used linear motors. We had a prototype they mounted heat sinks vertically and had the issue I described with the top side heating up. We had to mount them flat, and they stopped having overheating issues, they were dissipating heat more evenly. Apples to oranges I guess, those were running a ton of power through those things and they were in a more confined area. I assumed the concepts were similar.

Carts and horses, my friend; The only reason I made cylindrical trellis for HID lamps was due to their omnidirectional output. They did not happily fit in square cornered spaces and they were cramped inside, making them a bitch to work with. Worst of all, the round shape made for a far more cramped and less productive canopy, due to excessive self shading.

Because COB LED is generally directional in nature, there's no longer any need to curve the trellis panel, any more than there would be for a horizontal panel under a COB LED array. In fact, you're in effect making the case that flatlander style grows under HID lighting should curve up on the sides!

I built my light modules to be able to operate them beside or above the canopy, and to be able to space them apart as needed to achieve a desired light intensity across the target surface. I find the basic rules of these tasks differs very little between vertical and horizontal canopies; the physics of light distribution don't change with orientation.

Taking this a step further, I also employed 80 degree glass lenses to help focus the light more directly on the trellis panel and scatter less sideways. This again lessens the need for curving the panel- and provides protection for the chip which would otherwise get sprayed and bumped. Even with this feature, on the occasion a module in the middle of the array has failed there is still plenty of side lighting from other modules around it to grow good bud.

Answering the second question, these boards are big, thin and low power and they have a large surface area to watts ratio. Convective cooling will have more of an opportunity to make a difference in operating temperature.

Hallways are much easier to work in and build into conventional indoor spaces;

Would you happen to have a log of how you went about putting it all together or how you came up with the design.

I've got a question for the vert growers. Do you find yourself accidentally blinded by the light more often or less often than when running horizontal? I'm assuming everyone is wearing sunglasses, but still. How about bumping into your lights? The last time I tried vert with a bare bulb 1000 I melted some athletic shorts onto the bulb:wall:. Thankfully cobs run much cooler.

Just calculated the square foot for my room horizontal 56 vs. vertical 78+ bongsmilie

I can't answer that, I don't run flatlander style.

I got lenses on my COB LED specifically to avoid any damage when they get rubbed on. They're never more than warm to the touch.

That's why airlines suggest wearing cotton clothing when traveling. Think about it...

Well I've been plowing through that other thread but 180 pages is going to take some time.

Any who, ttystikk and who ever else is watching what's your opinion on mineral oil cooled leds ? lol
